Answer:
Regulatory sites e.g enhancers and silencers
Explanation:
Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.
Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.
Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
<h2>Tetrapods</h2>
Explanation:
d. All of the above
Tetrapods include animals who have four limbs.
Tetrapods are thought to evolve from aquatic ancestors, and primarily inhabited shallower waters before they completely migrated to land. This transition has fascinated the scientists and created a wild field for evolutionary studies.
Phylogenetic analysis prove that, tetrapods are advance and more complex than non-tetrapods, they are more evolved than non-tetrapods and are closely related to each other.
C, prophase. It’s when the DNA duplicates and and centrioles begin to form I believe.

Answer:
Synthetic rubber.
Explanation:
Polymerization can be defined as a type of chemical reaction in which molecules that are relatively small in size chemically combine to form a huge chain of molecules.
Simply stated, polymerization refers to a chemical reaction where two or more smaller molecules react to produce larger molecules of the same network or repetitive structural units.
In polymerization, the relatively small molecules are generally referred to as monomers while the larger molecules they produce are known as polymers.
Butanol was used in the production of synthetic (artificial) rubber through a fermentation process.
I’m pretty sure males are ZZ. Let me know if I’m right and have a good rest of your day!
